Heat, Temperature, & Thermal Energy
Transcript of Heat, Temperature, & Thermal Energy
Latent heat deals with the appearance of the particles, where as specific heat deals with the amount of heat per unit mass to raise temperature by 1 degree Celsius.
Temperature is the measure of how hot or cold a place or object can be.
Location and objects have a lot to do with temperature. There's body temperature, colder environments, and extremely hot environments.
There are three types of heat transfer.
Heat is defined as the flow of thermal energy, the transfer from a hot object to a colder object.
Convection: particles move via liquids.
Conduction: particles move via solids.
Radation: transfer of heat by electromagnetic waves.

Thermometers were first created by Gabriel Fahrenheit in 1714. Thermometers measure the temperature in matter.
There are 3 scales of conversion dealing with temperature.
The difference between heat and temperature is very subtle. Heat is a type of energy, and temperature is not. Temperature does not deal with the amount of mass and matter, as to where heat does.
Thermal energy is the rate at which the atoms or molecules are vibrating. Thermal energy is usually not visible but we can feel its effects. It is in most simple terms the kinetic energy of the atoms.
Examples of thermal energy!
The formula to calculate heat is: Q (the measure of used in Joules) equals m (the mass of the substance) multiplied by c (the specific heat) also multiplied by the change of temperature. Most commonly these measurements are used in Celsius degrees.
Objective: Students are able to identify and differentiate the difference between heat, temperature, and thermal energy. As well as giving accurate examples of each.
Essential Question: What is Heat? What is Temperature? What is Thermal Energy? And how do all three connect?
The difference between all three heat, temperature and thermal energy are the slightest things. Heat is what we feel, the degree of how hot or cold an object can be. Temperature is the measurement of the average kinetic energy. Thermal energy is how fast or slow the particles in the object are moving.
